P. variábilis Lamb. Pin., ed. 2., 1. t. 14.; and o u r /g . 1828. of the natural
size, from Lambert’s plate.—Mr. Lambert describes this pine as having the
leaves in twos and threes, 2 in. long, channeled, the margins and nerves rough,
and the apexes sub-keelshaped; the sheaths short, straight, and but little
wrinkled. The cones solitary, recurved, pendulous, narrow-ovate, muricate;
spines subincurved, with the scales dilated in the middle. He has only seen
two trees of this species in England ; one at Pain’s Hill, and the other at
Kew. (Lamb.) The one at Kew no longer exists; and the only trees at
Pain’s Hill, that we could see, with cones resembling
those in Mr. Lambert’s plate, had three leaves,
and appeared to us to belong to P . Pse'da. ^ The
buds in Mr. Lambert’s figure appear to be resinous,
and are nearly smooth (see/g. 1829.), but those of
P. variábilis at Dropmore, which we feel confident is
the P. mitis of Michaux (which Mr. Lambert makes
a synonyme of his plant), are scaly, with the scales
reflexed, as in Jig. 1810. in p. 974. The young
shoots in Mr. Lambert’s plate are green, but in the
Dropmore plant they are of the same violet glaucous
hue as those of P. inops ; a character so
remarkable that it cannot be mistaken, and which,
Michaux says, belongs to no other pine of the United
States but P. inops and P. mitis. (N . Amer. Syl.,
iii. p. 130.) It is found also in P. Sabimàna and P.
1829. P . variábilis.

abilis may therefore be considered as an imaginary species, or as a synonyme
to p. mitis.

Spec. Char., f r . Leaves three in a sheath, much longer than the cones
flexible, tortuous, with short sheaths. Crest ofthe anthers rounded, entire’
Cones ovate, reflexed, with the apices of tlie scales flattened, with a raised
process in the middle, terminating in a conical, minute, recurved spine
slightly quadrangular. Buds, in Douglas’s specimen, | in.
long, and f in. broad ; cylindrical, with straight sides, rounded
like a dome at the extremity, but with a prominent blunt
point ; dark brown, and covered with resin. Buds, on tlie
living tree in the Horticultural Society’s Garden (see Jig.
1830.), from 1 in, to IJin. long, and from fin . to Uin . broad;
smooth, cylindrical, with a long point; reddish brown, and
covered with a fine white bloom, consisting
of fine particles of resin, surrounded
by two or more smaller buds.
Leaves disposed in parallel spirals ; in
Douglas’s specimen (see Jig. 1832.),
1830. from 9 in. to 11 in. long ; 3 in a sheath,
which is from f in. to 1 in. in length,
lyith numerous fine rings ; scales of the leaves persistent
on the wood, even of two years’ or three
years’ growth. Leaves, on the living plant, from
7 in. to 9 in. long. The cone (see fig. 1831), in
Douglas’s specimen,
is deformed, and very
imperfectly developed
; it is only 3 in.
long, and J in. broad.
The scales are termi
nated inflattenedpro-
cesses,scarcelyribbed ,
in any direction. In
the centre of the process
is a protuberance,
large in proportion
to the scale,
which terminates in a
sharp prickle, pointing
outwards. Scale
